Take a little drink - yes, on the quiet (3)
I believe the answer is:
sip
'take a little drink' is the definition.
(I've seen this in another clue)
'yes on the quiet' is the wordplay.
'yes on' becomes 'si' (I am not sure about this - if you are sure you should believe this answer much more).
'the quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'si'+'p'='SIP'
Can you help me to learn more?
(Other definitions for sip that I've seen before include "Drink slowly" , "Take a little of a drink" , "Smallest drink" , "Take in slowly" , "Drink in tiny mouthfuls" .)
